High-frequency response of electro-optic single crystal KTa/sub x/Nb/sub 1-x/O/sub 3/ in paraelectric phase

Electro-optic constants of KTa/sub x/Nb/sub 1-x/O/sub 3/ can be up to 600 pm/V with a bias voltage. In this report, dielectric dispersion is investigated to examine the electro-optic effect in a 1 MHz to 3 GHz frequency range.
